An ignition coil for an ignition system of an internal combustion engine includes a primary winding connected, by an electrical connection, to a generator, and a secondary winding connected to a spark plug and including a plurality of turns of capillary wire covered with an insulating layer and wound on an electrically insulating support. The support includes a receiving seat in which there is inserted a terminal to which an end portion of the capillary wire is anchored. A connector includes an elastic clip contact element that is fitted on the terminal and is provided with a cutting element to cut the insulating layer of the capillary wire. A stop device prevents the elastic clip contact element from closing beyond a determined amount or entity. An abutment body abuts on the terminal to establish the electrical connection between the capillary wire and the terminal.

An electrical contact system includes a contact having a barrel with a wire entry portion having a first diameter, a clip portion having a second diameter, and a cam portion having a second diameter at a first end that tapers to a third diameter at a second end near the wire entry portion. The system also includes a clip positioned in the clip portion of the barrel, wherein ends of inwardly directed tines of the clip are configured to engage the conductor to enable the clip to be drawn onto the cam portion in response to a user pulling the wire after insertion of the conductor through the clip.

A powder-driven connecting tool for connecting power lines is disclosed, as are assemblies and replacement parts for such a tool. The tool includes a tool head with an anvil, and a power unit with a ram. A breech cap assembly connects to the power unit and includes a sleeve threaded on both ends and a cap threadedly mounted on one end of the sleeve. The sleeve and cap define a breech for a powder charge. An adapter is mounted on an outer end surface of the cap. The adapter is narrower than the cap itself and is adapted to be driven by a power tool in order to tighten and loosen the cap and the sleeve. The adapter may, for example, have the form of a hex nut.

The invention relates to an electric device, especially to a tool used for connecting busbars, said tool comprises an hydraulic cylinder antriebseinheit and an electric control unit, a stationary portion removably connected to a busbar, a movable portion removably connected to a busbar and a loading portion for clamping connecting rods. Said movable portion is movably connected to a first and second stationary shaft of said stationary portion, said movable portion is fixedly connected to said hydraulic cylinder antriebseinheit by a movable shaft, said movable shaft is driven to slide axially with respect to said first and second stationary shaft by said hydraulic cylinder antriebseinheit, said loading portion is movably connected to said second stationary shaft and slides between a body of said stationary portion and a body of said movable portion, said loading portion rotates around said second stationary shaft. It is achieved that a plurality of connecting rods are simultaneously mounted to busbars and that two busbars are connected in a form of butt-and-butt connecting.
